6 Claims.

This invention relates to calendars and particularly to a long termcalendantV A calendar of the present invention comprises,

preferably, a plurality of members, operatively.-

related to each other in 'a manner wherebythe chart or showing for any month in any year indicated onrthecalendarmay be easily and quickly determined, andk one of'. the objects of the present invention is to provide a calendar comprising the .combination of a pair of members having suitable indicia thereon and which are relatively movable for the purpose of bringing the indicia on the respective members into .proper Voperative relationship for obtaining the condition desired.

Another object of the invention is to provide a calendar of the-character described in which a novel arrangement of indiciais provided on the front -sides of the .respective members in a manner whereby the results sought may be readily rand conveniently obtained.

Another object ofz-the invention is to provideI a calendar infwnich the thirty andY thirty-one day monthsare' correctly.v given, including information by which the correct number of days for the'fmonth `of February can be determined whether in a leap year. or other year.

Another `objectof the invention is to-provide` a. calendar in which kthe indicia provided thereon is arranged in .a manner to insure proper relationship of the respective members, and wherein it is practically impossible to obtain an incorrect reading of. the calendar when the members are properly adjusted With respect to each other.

A further object of the invention is to provide means by which one may be informed as to' the limits to which one of thezmembers is intended to be moved or otherwiseshifted withrespect to the other member in order to prevent improper positioning of one of the members with respect to theother member.

A still further object of the invention is to improve devices of the character describedin sundry details hereinafter referred to and particularly pointed out-in the appended claims.

One embodiment of the present invention is shown for illustrative purposes in the accompanying drawing in which:

Fig. 1 is a face view of a long term calendar y comprising a pair of. operatively related members embodying features of the present invention, a portion of the structure having been broken away to permit of showing the remainder of the structure'on as large a scale as possible;

Fig'.` 2 is a face view, on a slightly reduced scale,

of one of* the members shown in` Fig.- 1 with the other member removed; and

Fig. 3 is an elevationalor edge view,partly1inf= section, on-a reduced scale of' thestructure illus-w trated in Fig. 1, a portion of Fig. 3 being shown A inv section-to' more clearly illustrate the manner of securing the respective' Imemberstogether and 1 the present instance, Yas-operatively connected-A together in pivotal relationship by means of. Va ferrule or trunnionl I-, and in a manner to permit of relative rotation of. the -members with respect l to each other; Forvi convenience in describingv the present structure it might be helpful to observe here that'lthe member may be referred 1 to as a relatively-fixed lor face member and the member 9 as a rotatable or subjacent member.`

With this observation 'in mind,the face memberr i 8 may .bedescribed as formed of card-board or other suitable material and provided with aplur rality of elongated 'radially extending annularly spaced apertures .indicated respectively by the numerals I2 to I8, inclusive; and having indicia designating the days of the week, preferably, adjacentone: end` thereof.

Formed also in the member 8' are a plurality of apertures I9 and 2| disposed,preferably, at opposite sides of the Ypivotal center ortrunnion I I and havingindicia vdesignating a pluralityl ,of years, Such as "1936*k and A1937 therewith.

Thermember 8, `preferably adjacent its lower edge portion, bears a plurality Yof radially dis-f posed annularly spaced -alternating relatively short-and--long columns or banks of indicia desig-` natingfa. plurality of years and indicatedV by the numerals 22 and 23,-respectivelyftheshort columns 22 shown in italic being leapY yea-rs and the longer colum-nsf23--being years other than the leap years,thelong columns being alsoidentifle'd adjacent their upper endfpo-rtionsby the indicia numerals I to -'I, respectively,

associated The lower edge portionbithe member 8,in

the present -instancefiis kshown as of v'subst-antially arcuate form-and provided witha plurality of alternating recesses'24: and lprojections-5 arranged, respectively, adjacent vthe lower ends of and 'substantially lin radialcalignment with the relatively shortand long vcolumns of years 22v and 23.

Referring particularly'v to.-Fig;-.2 of the' drawing, it will be noted that the radially disposed apertures I2 to I8, inclusive, apertures I9 and 2I and the alternating recesses 24 and projections 25 are shown in dotted lines thereon, and that the rotatable or subjacent member 9 shown in Fig. 2 is provided with an aperture 26 adapted to receive the trunnion II in a manner to rotate thereon, and is provided with indicia comprising a plurality of numbers designating the days of the month and indicated as a whole by the numeral 2l, the said indicia numbers being arranged in arcuate radially spaced lines and in radially extending annularly spaced columns with respect to the aperture 26, the numbers being successively or consecutively duplicated in the respective lines except the number 3|, which appears but once in each of the two outermost arcuate lines, the said indicia numbers 21 being adapted to register with the apertures I2 to I8, respectively formed in the member 8 in a manner to appear as radially disposed annularly spaced columns under the respective days of the week appearing on the member 8 adjacent the upper end portion of the openings I2 to I8, respectively.

Adjacent the opposite ends of the lines of indicia numbers 2l are indicia reading Stopl turn back which, when brought into register with either the opening I2 or I8, will indicate that the member 9 has been moved too far to obtain a proper relationship of the indicia thereon, thereby providing means for indicating the limits to which the members 8 and 9 may be properly moved relative to each other.

Immediately outside the lines of indicia numbers 2l are a plurality of arcuate columns of indicia containing the months of the year and indicated by the numerals 28 and 29, the said columns being positioned, preferably, at opposite sides of the aperture 26, the months in the columns 28 and 29 being duplicated and adapted to register, respectively, with the openings I9 and 2I formed in the member 8 and designated by the indicia 1936 and 1937.

Adjacent the upper ends of the arcuate columns of months 28 and 29 are indicia reading Stopl turn back which, when brought into register with either of the openings I9 or 2l, Will indicate also that the member 9 has been moved too far to obtain a proper relationship of the indicia on the two members, thereby providing additional means for indicating the limits t which the members 8 and 9 may be properly moved relative to each other.

Outside the arcuate columns 28 and 29 are a plurality of radially spaced lines of months, indicated by the numerals 3I and 32, respectively, the months appearing in line 3| being duplicated except the months of January, April and July, and the months appearing in line 32 being duplicated except September and December, the months specically named appearing but once in the respective last mentioned lines.

The months in line 3l, it will be noted, appear in italics and are adapted to register With the respective recesses 24 formed in the lower edge portion of the member 8 in operative relationship with the relatively short columns of years 22 appearing also initalics onV the member 8 adjacent the said recesses 24, the positioning of a month appearing in line 3I in'register with a particular recess provides a proper relationship of the members 8 and 9 to designate the particular month in a leap year or years appearing .in an adjacent column 22 in a manner to-position the days of said month in that particular year or years in proper relationship with the openings I2 to I8, inclusive, formed in the member '8 toindicate the days of that particular month and year or years in proper relationship with the days of the week as defined by the openings I2 to I8, inclusive.

The months in line 32, it will be noted, appear in upper case letters and are adapted to register With the respective projections 25 formed on the lower edge portion of the member 8 in operative relationship with the relatively long columns of years 23 appearing on the member 8 adjacent said projections, the positioning of a month appearing in line 32 in register with a particular projection provides a proper relationship of the members 8 and 9 to designate the particular month in a` year other than leap year appearing in an adjacent column 23 in a manner to position the days of said month in that particular year or years in proper relationship with the openings I2 to I8,V inclusive, formed in the member 8 to indicate the days of that particular month and year 'or years in proper relationship with the days of the Week as defined by the openings I2 to I8, inclusive.

In the operation of the device, the member 9 may be rotated so that any particular month appears under one of the columns of years 22 or 23 in which a date is desired, which will give that complete calendar month in that particular year. For example, for the rst month of the year 1936, turn the member 9 so that the month of January appears in the opening I9 adjacent the indicia 1936, or so that the month of January in line 3| of the member 9 appears in the recess adjacent the column or bank of years 22 in which 1936 appears, and shown, in the present instance, as the short column between adjacent longer columns under the indicia 3 and 4. This Will give the month of January, 1936, and in this same position, the calendar is set for July, 1936, and December, 1937 (see Fig. 1). By referring to the outer portion of the member 9, the months appearing thereon are correct for all the years in the columns of years which appear above said months. In the column designated by the indicia I, the years 1850, 1861, and 1867 so on downl to 1957 are shown, and on member 9, line 32, under this columnappears May. This gives the correct calendar month for May in all of these years, the month starting on Wednesday, and having thirty-one days. In the same position, the calendar is correct for January and October in all the years in column 2; July in all the years in column 3 and so on to August in the years appearing in column 'I. The leap years in the relatively short columns 22 are in italic figures as are also the months for the leap years appearing in line 3l, and it will be apparent that by leaving the member 9 in the position above described, the month of August, for example, is shown directly under the first relatively short column 22 containing the years 1860, 1888, 1928 and 1956, in which the month of August in all of these leap years is shown as starting on Wednesday with the first of the month and ending with Friday, the 31st.

It will be observed from the foregoing description that the present invention provides a long term calendar on which suitable indicia and sight openings are arranged on the front sides of relatively movable members, whereby desired results may be obtained, and wherein the said members may be readily and conveniently posi- Cil tioned vwithl respect to eachother, whereby Vthe calendarwill properly showtheldays of the Week and month for any month of any year indicated on the calendar. v 'I Furthermore, it Will be apparent that the present invention insures the positioning of the relatively movablemembers in proper relationship withl respect to each other in a manner to obviate the possibility of obtaining an incorrect reading of the columns when the members are properly adjusted with respect to each other.

Obviously, the present invention is not limited to the precise Aconstruction and arrangement shown and described, except as the same may be limited by the appended claims. Moreover, all the features of the invention need not be used conjointly, as the same may be used to advantage in variously different combinations and subcombinations.
